An arch tray for topical treatment of the teeth and/or adjacent gum areas comprises a horseshoe-shaped element of a resilient non- absorbable pliable material, for example closed cell polyurethane foam material. In the top of the element is formed a groove adapted to accommodate a topical agent and the teeth of a patient, the groove terminating short of the free ends of the element and being of greater width in the posterior or side portions thereof than in the anterior or central portion thereof. As illustrated in Figure 1, arch tray 10 comprises anterior portion 11 and contiguous posterior portions 12 at the free ends of which are laterally widened bulbous portions 13 serving to contact and restrain the tongue. Groove 110 is of enlarged width 120 in the posterior portions and terminates short of the free ends thereof to provide abutments 14. As illustrated in Figures 4 and 5, a reservoir 1100 preferably is formed in the bottom of the groove and is of enlarged cross-section 1200 in the posterior portions of the element. One or two arch trays may be used separately or simultaneously in treatment, for example fluoride treatment, of the teeth, the reservoir being filled with a suitable treatment agent, preferably in gel form.

Title: Silicate resins
Inventor: COATES HAROLD
IPC: C08L83/16
Filed: 1965-11-30
Abstract: A resin precondensate is obtained by the partial transesterification of an organic silicate with at least one organic polyhydroxy compound (either or both of the silicate and polyhydroxy compound containing aromatic groups) in the presence of a base and formaldehyde or a precursor thereof.  The reaction is usually carried out until the reaction mixture begins to gel or, where a solvent is used, until the reaction product begins to precipitate out from the solvent.  Further formaldehyde is added to the precondensate, unless sufficient residual formaldehyde is present therein, to effect final cure of the product.  In Examples, bisphenol A and/or hydroquinone was reacted with phenyl- or ethyl-ortho-silicate and hexamine.  The product of Example (2) was a brittle foam.  Uses.-As laminating, moulding or coating compositions.

Filed: 1965-12-01
Abstract: 1,076,329. Container closures. SCOVILL MANUFACTURING CO. Dec. 1, 1965, No. 50956/65. Heading B8T. [Also in Divisions F1 and F2] In a container closure, an aerosol valve allowing both filling and discharge of a pressurized container comprises a cap 17 supporting a cylindrical housing 12 having a chamber 13 containing a valve member 15 spring-urged to engage an annular elastomeric seat 14, the latter being a tight fit on the tubular stem 31 of the valve member so it adopts a dish-shaped configuration when assembled. The perimeter of the upper part of the housing 12 is provided with longitudinal recesses (27) (Fig. 6, not shown), adjacent a portion 35 of the cap, and the upper end of the housing is castellated. In the closed position shown, the inner periphery of the elastomeric seat 14 seals a clearance 39 between the cap 17 and the stem 31, and the outer periphery seats on a shoulder of the housing 12. A bore 32 communicates with the interior of the stem and the space between the underside of the seat and the top of a part 30 of the valve member 15. To fill the container, a tubular filling head (44), (Fig. 3, not shown), is placed in sealing contact with a portion 35 of the cap 17 and gas initially passes into the stem 31 to depress the latter and allow gas to enter the container via the bore 32. However, once the stem has been depressed, the gas pressure acting on the annular clearance 39 depresses the seat 14 to a position where it closes the bore 32 but allows flow into the container via the castellations and recesses (27). To discharge the container, the stem is either depressed or tilted (Fig. 4, not shown), to allow the contents to escape via the bore 32. Protuberances (46 or 47), (Figs. 9 and 10, not shown), may be provided on the valve member 15 to support the seat.

Preferably the pulses are applied by electron beam which may be swept over the treated surface; alternatively or in addition the surface may be moved in relation to the beam. In a particular embodiment, an X-ray target 2 is rotated by induction motor 15 while an electron beam from filament 17 impinges on the focal track, the pulses being produced by solenoid switch under control of timer 39. In a further embodiment, Fig. 2, the electron beam is deflected by plates 47, 48 over a water cooled static target 49.

Abstract: 1,163,366. Furnace charging apparatus. ALLIANCE MACHINE CO. 9 Nov., 1967 [14 June, 1967], No. 51047/67. Heading F4B. Apparatus for charging a converter 10 with both scrap and molten metal, comprises a wheeled support structure formed of gantry legs 14, beams 17 and end ties 18 and 19, running on trackways, both on the floor 11 and on a beam 12 mounted above the floor, between a loading area (not shown) and the furnace charging area. The beams 17 support between them and provide a trackway 20 for a wheeled trolley 21 which carries hooks 24 adapted to engage with the trunnions on a molten metal ladle 26, or the trunnions on a scrap box 28, and also an auxiliary hook 30 adapted for tilting the molten metal ladle. A tiltable platform 36 on which the scrap boxes 28 rest, is carried between the gantry legs 14, which platform may be tilted by a pistoncylinder arrangement or by hoist 39 and cable drum 40. In operation, in the loading area, hooks 24 are used to load a fresh scrap box 28 on to platform 36, and then to pick up a ladle 26 filled with metal. The apparatus is then moved to the charging area opposite the tilted converter 10, the platform 36 raised and tilted to discharge the contents of the scrap box 28 into converter 10, the platform 36 relowered and the ladle 26 tilted to discharge its contents into converter 10 after movement of trolley 21 along the trackway 20 to a position adjacent the converter. The apparatus then returns to the loading area to receive a fresh charge of scrap and hot metal. In a modification, (Fig. 3, not shown), the girders are supported at both ends by wheeled legs extending from the floor.
